In bconfig.c, the following should be reworked:

        { "mirrormode", "on|off", 2, 2, 0,
ARG_DB|ARG_ON_OFF|ARG_MAGIC|CFG_MIRRORMODE,
                &config_generic, "( OLcfgDbAt:0.16 NAME 'olcMirrorMode' "


So that the parameter name is multimaster, and the config attr is
olcMultiMaster

The term "mirrormode" is both confusing and misleading, as what it really
controls is whether or not this node is enabled for multimaster.
